| 摘 要： | 采用层层组装方法(LBL),将纳米方钠石分子筛进一步修饰到经镍(Ⅱ)四磺酸基酞菁(NiTSPc)和全氟磺酸离子交联聚合物(NafionR)修饰的玻碳电极(GCE/NiTSPc/NafionR)表面上,制得一新型NO传感器GCE/NiTSPc/NafionR/(PDDA/Zeolite)5 (PDDA即聚二甲基二烯丙基氯化铵),并对其电化学性能进行了研究.结果表明,纳米方钠石分子筛修饰膜不仅可提高电极检测NO的灵敏度(由26 Ma/(mol·L-1)升至29 Ma/(mol·L-1)),还可提高电极抵抗共存物干扰的能力.Nafion修饰层可使电极对抗坏血酸、多巴胺、肾上腺素及亚硝酸钾的响应分别降低19%、0%、11%、33%,而进一步修饰纳米方钠石分子筛后,电极对上述干扰物质的响应分别降低了68%、51%、52%和39%.

| Abstract: | A novel nitric oxide(NO) sensor of GCE/NiTSPc/NafionR/(PDDA/Zeolite)5 was prepared by electrodepositing nickel tetrasulfonated phthalocyanine(NiTSPc) nano-sized sodalite zeolite with layer-by-layer assembly technique.Its electrochemical performances toward NO and some interference such as ascorbic acid,dopamine,epinephrine and potassium nitrite were investigated.The results anti-interference capability.After being modified with sodalite zeolite,the membrane only decreased 19%,0%,11% and 33%,respectively.Therefore,this novel electrochemical NO sensor provides an inspiring approach for NO real-time and in vivo measurement. |
